Oxygen 2

Oxygen 2 tells the story of the sea creatures on the transformed Coral Creek reef taking on a mechanical look. The concept asks whether these creatures, woven from flesh and metal, are evolving or being rewritten, and with the free demo you can see that underwater world first.

What kind of game is Oxygen 2?

This is an underwater-themed slot with cluster wins on a 6×7 grid. It includes multiplier features, symbol transformations, feature wilds, big symbols, a bonus, and a super bonus, with an official max win of 25,000x. As the second game in the series, it carries the signature fun of ELK Studios slots, where multipliers grow on the same cells.

How do the Oxygen Bubble and octopus work?

When winning symbols pop, the Oxygen Bubble in that spot is activated, or the multiplier of an existing bubble turns on. When a win lands on the cell with the octopus, it adds nearby multipliers to the win at random. If many bubbles are lit and a win lands near the octopus, the effect gets bigger. The presentation of the sea creatures turned mechanical is also quite unique.

What do the jellyfish and the two wilds do?

The jellyfish stops on a random number of cells and raises Oxygen Bubble multipliers, and it can raise its own multiplier too. When the Blaster Wild pops, it picks one pay symbol and turns an X-shaped or cross-shaped area into that symbol. The Blast Wild clears pay symbols in a left-right or up-down cone range, and the Super Blast Wild also lights the bubbles in the cleared spots.

How are the bonus and super bonus different?

Three bonus symbols start the Free Drop bonus, and existing multipliers carry over and stay for the whole bonus. The octopus also stays and moves to a new position with each free drop. Four bonus symbols open the Super Bonus, where the jellyfish feature triggers on every free drop. Each wild type changes the screen in a different way, so the anticipation for the next drop depends on which wild appeared.

What should I check first in the demo?

The figures confirmed in the provided material are a bet range of €0.20 to €100 and an official max win of 25,000x. RTP and the official volatility rating are not in the material, so please check the in-game info screen. In the demo, watching how widely the Oxygen Bubbles light up and how many cells the jellyfish stops on will show you the flow. The jellyfish feature is the key.
